JOHN A, PARKINSON, F SIOUX CITY, IOWA ACTUATING MEANS FORMOTOR-STARTERS.

To all whom it may concern Be it known that 1, JOHN A; PARKINSQN, acitizen of the United States, and a resident of Sioux City, in thecounty of Woodbury and State of Iowa, have invented certain new anduseful Improvements in Actuating Means for Motor-Starters, of which thefollowing is a specification.

The present invention relates to means for starting automobllegas-engines.

The invention has for its primary object the production of improvedactuating means for mechanical motor starters employing ratchetand pawlmechanism for turning the production Ofpit hand-lever: particularlyefiicacious and inexpensive both in manufacture and installation. I

' With these-objects in yiew the invention will be readily understoodfrom the follow ing description, reference being had to the'accompanyingdrawings which form a part of this application and in which likecharacters of reference indicate corresponding parts throughout thesew'eral views, of which,

Figure 1 is a fragmentary front elevation of an automobile'chassisequipped with the device of my invention; Fig. 2 is a. side elevation ofthe buffer; and Fig. 3 is a rear elevation of the hand-lever and membersassociated therewith.

Referring now, to the illustrations, the main-frame of the chassis isrepresented at at, andequiipped with the usual dash, 5, andstarting-crank, 6.

7 is a ratchet-wheel formed integrally with the fan belt-pulley, 8. Acollar, 9, freely encircles the shank of the hand-crank and "carries aradial arm, 10, provided on 1ts rear side with a pawl, 11, pivoted toengage the ratchet-wheel and having its heel, 12, normally engaged by astop, 13, on the frame, whereby the pawl is normally disengaged from theratchet-wheel. The lever-arm, 10, terminates in a segment, 14, to thelower end of which is attached a flexible link, 15. A spring, 16, theends of which are secured, respectively, to, the main-frame and thelever-arm, serves to retract the latter.

Specification of Letters Patent. Patented Sept. 28, 1915.

This application filed July 2,

The fragmentary structure above described represents no part of thepresent invention, but forms, in part, the subjectmatter of my copendingapplications 7 91,663, filed September 24, 1913; and84c8,673,' filedJuly 2, 1914, and serves to illustrate the utility of the presentinvention.

On the rear side of the dash and adjacentone edge thereof is an uprightshaft, 17

freely inclosed by bearings, 18, mounted upon the dash; The upperv endof said shaft is provided with a horizontally-disposed hand-lever, 19,and the lower end carries a lateral arm, 20, to the end ofwhich issecured the link, 15, passing around'a direction pulley, 2 1, andsecured ,to the arm 10 as previously described.

By virtue of the structure now disclosed it is clear that in startingthe mot or, the driver. draws the hand-lever toward him, therebyimparting traction upon the link 15 to actuate the pawl and ratchetmechanism.

When released the hand-lever is retractedv by the spring 16; and theshock incident to the retraction is reduced by a V shaped socket, 23,the arms of which tend to spring toward each other and engage oppositesides of the lever. The lever is so designed as to afford a greatpurchase, is within convenient reach of the driver yet never in his way,and is readily installed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

In an automobile motor-starter having a ratchet-wheel mounted on themain-shaft and a retractable radial arm provided with a pawl to engagethe ratchet-wheel, the combination of an upright shaft mounted upon thedash and having a lateral arm on its lower end and a horizontal leverformed on its upper end and normally disposed substantially inparallelism with the dash, a link between said arms, and shock-absorbingmeans interposed between the dash and ever. i

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN A. PARKIN SON.
